@Sinnlich,
I'm sorry , but WHAT"S WRONG WITH YOU - ok now i can see , i guess , why you went about it the way you did , but why couldn't you go see a marriage counselor instead of ,like you put it, "swinging" or trade partners, you brought this on yourself , and you're right your marriage might never be the same, i'm a married man and my wife and i were having intamacy issues and we talked about it and we were also in marraige counseling, however even if we were not in therapy to repair our issue i know niether one of us would go outside the marriage to have sex with someone else, i know she would have no part of it - PERIOD.
I don't know what you expect me to say to you but you brought this on yourself, now you have to deal with the emotions that come afterwards, jealousy is a BIGGY and getting over that is going to be tough, can you get over that, maybe, but its going to take time and lots of patience, how does your wife feel about all this, are you even talking to her about how you feel, if you're not, you need to , ASAP, otherwise you are in this alone and its going to be torture, if its not already, i felt pretty alone when we were having issues but we talked about it like i said, and we got through it, you can to, if you both are willing to do the work , the pain work, then yes you will be able to repair your marriage and things will slowly get better over time, i wish you the best, try not to beat yourself up and don't put your hands on her like you mentioned, because your relationship with her will DEFINITELY be finished, think about what you are going to say and sit down with her and talk with her, ASAP, if you want this to work you have to be patient, good luck.
